Ubuntu

Ubuntu is a well-liked desktop OS, which uses the Linux kernel, but its server edition is getting very popular as well. The main reason is the fact that the OS is extremely light and it will function on almost any hardware without any issues, utilizing its resources to the fullest. Ubuntu is also very reliable and secure and all of the Long-Term Support (LTS) releases are supported for a minimum of five years, which guarantees that you should have a risk-free and stable software environment on your hosting server at all times. In addition, Ubuntu has one of the largest user communities worldwide, which means that if you experience any problem or have any question, you will find lots of resources on the web. One of the major benefits of this OS is that it features thousands of software packages which can be easily modified in accordance with your needs as well as the requirements of the apps that you need to run, not to mention that you won't have to pay any license fees at all. In contrast, other Operating Systems are paid and their program code is not accessible, therefore it can't be changed.
